5.3.2 Head Ambient Temp. / Alarm Output
This output can be configured either as output for the head ambient
temperature (default configuration) or as an alarm output.
Figure 10: Wiring the Output for Head Ambient Temperature
The output range for the head ambient temperature is 0 to 500°C
(32 to 932°F) with 10 mV /°C.
In case of an alarm the output switches between 0 V and 5 V. The
alarm output is controlled by the target temperature or the sensing
head temperature.
